Same symptoms my brother had two weeks back. Add in waking up thinking he’d been ask for a few hours but actually slept fourteen.Our whole house got it a few months back. I’ve never had a headache so bad. 48 hrs without any let up. Kept me awake all night. Other than that I wasn’t too bad.
I was wrecked tired for the week though. I’d sleep on the couch for a couple of hours and after waking I’d want to sleep again 20 mins later. Never had an illness like it.
I had a right dose of the flu a few years ago and for me that was far worse. I felt like I was fecking dying for the first couple of days.
